[GEN-1485] fix: num of selected app bug (#1581)

This pull request includes changes to update UI labels, improve data
filtering logic, and standardize code formatting. The most important
changes include modifying the title in the `SelectSourcesContainer`,
updating the filtering logic in `useSectionData`, and enhancing the
`EMPTY_SOURCE` message.

UI Label Updates:

*
[`frontend/webapp/containers/main/sources/choose.sources/index.tsx`](diffhunk://#diff-5eba8e65b9945f09d70123675f6205d939f20cbc54ae21ff29dda89f6b63cfadL18-R18):
Changed the title in `OverviewHeader` from `OVERVIEW.MENU.SOURCES` to
`OVERVIEW.ADD_NEW_SOURCE`.
*
[`frontend/webapp/utils/constants/string.tsx`](diffhunk://#diff-6b7ecf63c9f57c564b2f2f5d7998fd2cc45aee9e4dfc71aeeeb8361a39ba66cbL78-R78):
Updated the `EMPTY_SOURCE` message to be more descriptive by adding "in
this namespace".

Data Filtering Logic:

*
[`frontend/webapp/hooks/useSectionData.tsx`](diffhunk://#diff-4be3e790a193b5fb82050c23380608aef1b9b0ea3f0a201ea87e2cb8e620f7daL10-R15):
Enhanced the filtering logic in `useSectionData` to exclude items with
`app_instrumentation_labeled` set to true.

Code Formatting:

*
[`frontend/webapp/hooks/useSectionData.tsx`](diffhunk://#diff-4be3e790a193b5fb82050c23380608aef1b9b0ea3f0a201ea87e2cb8e620f7daL1-R1):
Standardized import statements to use single quotes instead of double
quotes.
